T45: Cmd-press, Ctrl-press off macOS, opens links inside herdr too: herdr wraps a long URL at its pane's edge and passes no OSC 8 target on, so the app opened a cut URL or nothing; while herdr's client leads the session and tracks the mouse the press goes to herdr, which opens its pane's link whole and underlines it under the key, Cmd heard as Ctrl on macOS; elsewhere the app opens links as before
